Has there? I've not noticed them. I turned my stop start off at the weekend via forscan.  Think the dual mass flywheel is just starting to vibrate. Less stop starts so hope the flywheel lasts a little longer. Also 95% soc made a huge difference to the way the car starts.

Is that an option for all Ford vehicles or just some wirh FORScan ?

I'm using the little electronic unit that copies the switch action and turns mine off 10 seconds after the engine has started. I had looked at trying to disable it with FORScan but didn't find an option.

No idea, know forscan can do focus MK3 I had before the Mondeo.

Hi Unofix what little electronic unit is that and how do I get one. My stop/start is a right pain it starts working within a couple of a hundred yards of driving even if the battery voltage is down around the 12 volt mark. It has never failed to work from new.

My 69 fiesta st passenger keyless entry and stop start stopped working and didn't know why but I wasn't doing much mileage then had a good drive out and all is working again 👍

I have a 23 month old Fiesta Titanium with 13000 miles on the clock. It had its first service 3 weeks ago and since then I've noticed that the Auto Stop/Start doesn't work.

On the dashboard display there is a circular icon with a capital A inside which has a line through it and it is  greyed out, which appears to  indicate that the Auto Stop/Start is disabled

If I hold the clutch down the icon disappears but it reappear once I release the clutch provided the car is stationary. 

Also there's a button with the same icon located behind the gear lever. If I press this button it illuminates in yellow to say that it is OFF and the dashboard icon disappears . If I press the button again the grey icon reappears 

Previously, when the Auto Stop/Start was working, the dashboard icon was  lit in green -- not greyed out.  

How can I enable the Auto Stop/Start and if I can't what is the likely reason for it not working now ?

Hi

My best advice is, get the battery charged fully (Halfords sell a battery Charger for around £30 that won't over charge it etc) and leave it on until the display says full.

Once full, reset the battery Control Module (BCM) - to reset, ignition on, flash the high beams 5 times, then press brake pedal 5 times. If the reset has worked, the battery logo will flash a few times. This tells the car the battery is fully charged and to take advantage of it. 

My issue regarding a battery drain on my Focus 2022 has taught me a lot about this from other clever people.
